In our modern world, working is a vital part of our lives. It is necessary in order to proceed with our lives. However, working should be a tool for our dreams and for a better life, it should not be our aim in life. However, some people could be a work-addict and they love working long hours and they only see the benefits of working long hours such as a promotion or more income. Working long hours and leaving very little time for leisure activities can be an obstacle for our dreams and for our health in long term. If we consider both advantages and disadvantages, the disadvantages will overweigh.
